So first you have to add all of the sides and then you have to multiply
Hope it helped
The GCF is 5 so the new expression would be: 5(x+2)
So discount means taken off
we find 15% of 199 and subtract from 199
% means parts out of 100 so 15%=15/100=1.5/10=.15/1=0.15
'of' means multiply
15% of 199=0.15 times 199=29.85
discount so 199-29.85=169.15
answer is $169.15
